I am unable to connect to the Internet using a wired connection. I was able to use the wired network yesterday. But I had problems with the flash player, so had to reinstall Ubuntu again. I am able to connect to Internet using wireless connection. But I need to connect to the wired connection. I am using Ubuntu 10. In my IPv4 settings, it is automatically set to DHCP, using which, I was earlier able to connect. But now it doesn't seem to be happening.

I have been trying to connect to the internet with a wired LAN connection for a while now with no luck. Running version 8.04 LTS on a 32-bit desktop. Interestingly, my 64-bit desktop running version 8.04 64-bit automatically connected to the internet with no problems or input from me. Both are connected to the same router.

I figured i'd try and copy the network manager settings from the 64-bit machine to the 32-bit machine, which involved setting an automatic configuration (DHCP}. All went well except no DNS server address showed up on the 32-bit system, despite there being one on the 64-bit system. Trying to run Firefox like this results in the 'page load error' page coming up immediately.

I then manually added the DNS server address from the 64-bit system to the 32-bit system, and all that did was prolong the time it takes for the 'page load error' page to appear.

I have just installed a fresh copy of 9.10 on an older Compaq nc6000 laptop. I need some help getting my Linksys WUSB600N wireless adapter to function properly.

I have "half-way" connectivity, meaning that I can see (and connect to) my home wireless network but I can't connect to the internet (unless I use the wired connection). I have installed NDIS wrapper - no change

I recently installed Ubuntu 9.10 on my Dell Inspiron 1545 64-bit laptop. Before that I used Windows7. In Windows, the internet connection worked perfectly well. But after installing Ubuntu, I am unable to connect to the internet. The network-manager applet finally says that "You are disconnected". When I do the "ifconfig", I got no IP address.

So, I installed Ubuntu 9.04 in the same system. But the problem persists.

I have just installed ubuntu 10.04 using the wubi installer to dual-boot my machine. Under ubuntu, I am not able to connect to the internet or my router. Everything works fine under windows. I have tried to find relevant information in the forums, but nothing seems to work for me. I have tried disabling ipv6, setting a static ip, but no go. ifconfig shows no IP, dhclient results in no DHCP offers and pinging my router's IP results in Network is Unreachable.

My laptop has been working fine with ubuntu 10.04, and earlier today it shut down after running out of battery. I came to use itr and discovered that the wifi icon had disappeared from the panel bar, and it won't connect to the wireless networkor via a wired connection.I have had a play around with this, tried ping -c5 google.comresult was:ping: unknown host google.comand ping -c5 4.2.2.1result: onnect:etwork is unreachable.I have other computers connecting to this network and know that it is working fine.

I have recently installed Ubuntu lucid lynx and at my old house I had a regular cable modem (no wifi) and never used wireless internet. I would simply unplug the ethernet from the windows desktop plug it to my laptop and I was good 2 go.have recently moved and my roommate has a cable modem w/ wifi capabilities. When I plug in I am told that I am connected but......Nothing. dont know if the problem is due to the modem having wireless capabilities when my old one did not or the fact that my roommate has a win7 laptop that is connected via wifi etc. There have been a FEW times that I have walked out plugged in and everything has ran well. when I do plug in I look under connection information and I am told that I am connected at 100Mbps but whenever I try to visit a page I am out of luck. I define newbie (as far as Linux distros) and I have tried everything including going to work w/no sleep because I'm going through massive trial & errors

I have 2 workstations that I'm trying to network together so that I can backup each to the other. One is XP sp2 and the other Fedora 9. Since installing Samba on the Fedora box and trying to get it configured, I have a problem that Add/remove programs won't do installs because it says there's no connection to a network. Network Manager says there aren't any connections, but it worked before the Samba install. Mozilla and Thunderbird can access the internet OK. Both workstations are connected by cable to my router and thus to my ISP (DNS server).

Two questions:- where can I find hints on setting up a wired connection (which card's MAC address does it want? router or wrkstn?) and Am I right that Add/remove is stuffed because of Network Manager?I now have Samba working from Linux to XP, but still can't get into Linux from XP. I tried the Linux PC's MAC address and set up a wired connection in Network Manager. NM still thinks there isn't one...

I just installed Fedora 10 for the first time on my HP Pavillion desktop. Everything worked fine and I installed the first set of updates. Then I wanted to install KDE so I did that. Then it told me there were more recommended updates. After installing KDE, I started to install the updates and when I came back today the wired connection wasn't working

i have just installed ubuntu 10.04 on my laptop hp 550.after i finished installation i connected to internet via eth0 wired connection normally and everything was fine...after about 1 hour i had no internet....i try restart but is the same problem....this is strange because my eth0 says connection established and when i open mozilla i cant open google either..when i ping [URL] it says "cant resolve "

my internet works fine in windows so what should i do to have back my internet on ubuntu...i cant do anything else in ubuntu if i have not internet and i like very much ubuntu so

I just installed ubuntu 8.10 on my pc. Before was XP installed. I formatted the system and installed ubuntu. Installation was successful. Problem is that I cant connect to network. My network card: realtek 8139 ethernet card

Also the connection is wired one with modem only it's reliance broadband. The wire is connected between modem and pc but there is no blinking of light for this connection. The wan is active and wan's light is blinking and when I was on xp on same pc there was no such problem.

The situation is I have one machine just installed 10.04yesterday, and I plan to take it as FTP server sharing filesvia LAN and WAN as wellBut after setting up all network withNetwork-Manager found that my dsl connection willdisconnect while my wired connection was connected.

I keep losing internet connectivity from within OpenSuse. I've had ubuntu/kubuntu beforeand never had a problem. I installed opensuse and now after a few minutes of browsing I'll lose my internet connection.I also dual boot into winXP without any problems.I noticed that when the connection is lost I can't even reach my router - which is where I'm getting the wired connection from.So it's not just the outside internet but the local network too. It only happens within opensuse.

After installing UNR onto my dell mini 9 and downloading the correct drivers to enable wireless internet (using this site: [URL]), I decided to load ubuntu onto my brothers netbook. After the installation completed, I went to do complete the steps listed in the above article, however I was unable to connect to the internet using an ethernet wire.

I have BIG troubles trying to set up wired internet connection in Ubuntu! To be able to connect to the internet I have to enter my MAC address, 2 IPs, netmask and 2 DNS address. When I try to edit the default internet connection eth0 with my correct information, the minute I enter my MAC address and save the changes the network manager creates new internet connection with wrong data and use it instead! I can't select the correct internet connection from the top bar where the internet icon is, because it is just not there. The only connection that I can choice is the new default one with the wrong data! If I try to create new separate internet connection with my correct data the same thing happens! The moment I enter my MAC address and save it, the internet connection disapears from the list of internet connections in the internet area in the top bar and I can't select it. I tried googling it, but with no luck I think that if I set up my connection trough the terminal everything will be ok

I have had the exact same set up 10.04 on the same machine connecting to the net with no problems. I had upgraded from an earlier version.

This time with a fresh install from disk the network manager does not see any connections. How can I get the manager to recognise the network and connect to the net?

I realise that it would help if I posted up the output of some commands in a terminal but I am writing this on my phone and can not cut and paste large chunks of text. I can only hope for some advice until I can get to a computer with a working connection.

I have an old Compaq Presario v2000 that recently had Ubuntu 10.04 installed on it. The wired internet worked when it was installed, but the wireless didn't. I tried to download the drivers for it and it failed everytime. I did an update thinking that the update might fix the wireless, but it didn't, it actually made my wired connection stop working. So now I have a newly installed OS on the laptop, and I can't do anything on it because there is no way to get any internet.

I've just installed the 64 bit 10.04 onto my new netbook, with ample specs to run the full desktop version rather than the stripped down netbook version. My only problem (at the moment) is that my wired internet connection is not recognized within the operating system, yet while I was downloading/installing Ubuntu it had no problem finding and using the connection then. When I boot into Windows 7 or plug the ethernet cable into my Mac, the connection is established immediately, and no need for manual entering of anything because everything is auto-detected. The really strange thing is I've run Ubuntu off a USB stick and when booting off that the wired connection was immediately recognized after startup.
